Gary, How long have you been on the list?
The Hanna TDS1 meter DOES NOT MEASURE PPM. The name TDS stands for totally dissolved solids, and CS IS NOT a totally dissolvedsolid. We when throught that about two months ago. Some thing that will measure PPM is a spectrophotometer or an Ion Selective Electrode. Both of which are many bucks.
